Kate Middleton was on a visit to the Mauristhsuis art museum as part of her tour of Holland.

She passed a royal rite of passage by travelling to the Netherlands to carry out her first ever overseas visit without hubby William.

She began by curtseying to the nation's king Willem-Alexander wearing a blue suit by Catherine Walker.

The visit comes a day after Prime Minister Theresa May was in the Netherlands for talks with her Dutch counterpart, Mark Rutte, to put forward her case for a fair deal for the UK with the European Union.

Mrs May also visited Denmark for talks with Prime Minister Lars-Lokke Rasmussen as part of her diplomatic offensive ahead of the formal beginning of the Brexit process.

Some commentators believe Kate will be an asset in helping to safeguard the UK's relations with its European neighbours as Brexit takes shape in the coming years.

The Dutch monarch invited the Duchess to lunch at Villa Eikenhorst, the royal residence he shares with wife Queen Maxima and their three daughters, Princesses Catharina-Amalia, Alexia and Ariane.

The family home is in the forested De Horsten estate in Wassenaar near The Hague, a former royal hunting ground which covers around 400 acres.

Despite being a private residence similar to the Queen's Sandringham estate in Norfolk, the Dutch monarch sometimes hosts foreign guests.

Kate followed royal protocol and showed her respect to the higher ranking Dutch monarch by curtseying, as she has done to other heads of state including the Queen.

The 34-year-old Duchess had planned to carry out her first solo tour abroad by visiting Malta in 2014 but she was forced to cancel because she was suffering from acute morning sickness while pregnant with Princess Charlotte, and William took her place.

The Duke of Cambridge was 27 when he carried out his first solo tour on behalf of the Queen in 2010, travelling to New Zealand to attend the opening ceremony for the country's new supreme court building, while his father, the Prince of Wales, made his first foreign trip on behalf of the Queen aged just 19.

Charles travelled to Australia to represent his mother at the memorial service for Prime Minister Harold Holt in 1967.
